SHORT STRUT
To provide a short strut that can be efficiently installed even if an excavation region is narrow.SOLUTION: A short strut 1A provided on an earth retaining support that is temporarily disposed on an excavation region 12 has a cylindrical outside strut member 3, rod-like inside strut members 4 (a first inside strut member 41, a second inside strut member 42) that can be inserted into or pulled out of the outside strut member 3, and can be switched between a reduction state where the inside strut members 4 are inserted into the outside strut member 3 and an extended state where the inside strut members 4 project from the outside strut member 3.SELECTED DRAWING: Figure 3
【課題】掘削領域が狭隘な場合でも効率よく設置することができる切梁を提供する。【解決手段】掘削領域１２に仮設される土留め支保工に設けられる切梁１Ａにおいて、筒状の外側切梁部材３と、外側切梁部材３に対して挿抜可能な棒状の内側切梁部材４（第１内側切梁部材４１、第２内側切梁部材４２）と、を有し、内側切梁部材４が外側切梁部材３に挿入された縮小状態と、内側切梁部材４が外側切梁部材３から突出した伸長状態と、に切り替え可能である。【選択図】図３
